High efficiency electric motor measures are taken from design, material and technology. For example, a reasonable number of stator and rotor slots, fan parameters and sinusoidal windings can be used to reduce losses, and the efficiency can be increased by 2% - 8%, and the average increase is 4%. In 2002, the total capacity of the electric motor in China was about 400GW, of which nearly 80% were medium and small, and the annual electricity consumption was 660TW H.
In order to save energy and protect the environment, high efficiency motor is the trend of international development. The United States, Canada and Europe have promulgated relevant laws and regulations. According to the CEMEP standard formulated by the motor running time in Europe, the efficiency is divided into three grades, eff1 (maximum), eff2 and eff3 (minimum), and is implemented step by step in 2003-2006 years. The latest IEC 60034-30 standards will be divided into IE1 (corresponding to eff2), IE2 (corresponding eff1), IE3, and IE4 (the highest) level. Our country has committed to the implementation of IE2 and above standards from July 1, 2011.
With China's entry into the WTO, the great competition pressure and challenge of the international community in China's motor industry are becoming more and more serious. From the perspective of international and domestic development trend, it is very necessary to popularize China's high efficiency motors, which is also the requirement of product development, making our motor products keep up with the international trend of development, and also help to promote the technological progress and product export of the industry. According to statistics, in 2002 China's motor power consumption accounted for more than 60% of the total power consumption, the power consumption of small three-phase asynchronous motor is accounted for about 35% of the power consumption, so the development of China efficient motor is one of the important measures to improve energy efficiency, meet the needs of the development of our country, is very necessary.
At present, China's industrial energy consumption accounts for about 70% of the total energy consumption, of which the motor energy consumption accounts for about 60%~70% of the industrial energy, and the energy consumption of the non industrial motor accounts for about 50% of the total energy consumption. And now the high efficiency and energy saving motor application is low. According to the sampling survey of 198 electric machines of the key enterprises in China, the proportion of high efficiency and energy saving motors with a level of more than 2 is only 8%. This is a great waste to the whole social resources.
